Supervisory Control and Data Acquisition (SCADA) system monitors and controls industrial process in physical critical Infrastructures. It is thus of vital importance that any vulnerabilities of SCADA system must be identified and mitigated. DNP3 is and open SCADA network protocol that is mainly used in electrical utilities. However, the security mechanisms of DNP3 were neglected at its design stage. For example, the coverage of DNP3 Secure Authentication is limited to itself only. In our experiments, we have successfully performed a number of attacks to DNP3 on a small-scale testbed. Hence, this paper will not only discuss our experimental results but also propose a novel hybrid method that can enhance the security of existing DNP3 protocol by combining both encryption and authentication techniques.
